[PATCH 32/42] dix: add real_event parameter to ActivatePassiveGrab

[Peter Hutterer]

For touch events with pointer emulation, the event that triggers the grab
(the pointer event) is not the same as the actual event (the touch event).
For replaying, we need to store the real event then.

No effective changes at this point, for the current caller event and
real_event are identical.
